Thermal Management: Thermal Management Design Guide Thermal Management Design Guide Thermal Management Thermal Management Design Guide Thermal Management Design Guide Thermal Management Design Guide Overview Incorporating thermal cooling within an enclosure can lengthen system life and increase control line reliability. The accumulation of heat in an enclosure is potentially damaging to electrical and electronic devices.
Thermal Management: Thermal Management Design Guide Thermal Management Design Guide Finding the Right Thermal Management Solution To determine the best thermal management products for the application, the user needs to define information about the environment, enclosure and the equipment inside. Use the form below in conjunction with Hoffman’s online Thermal Management Sizing and Selection Software.
Thermal Management: Thermal Management Design Guide Thermal Management Design Guide Internal Circulating Fans The graph below illustrates the temperature rise of two identical enclosures except one has an internal circulating fan. Each enclosure has two temperature sensors, one located near the top and the other near the bottom. The top and bottom black curves reflect the temperature in the enclosure without an internal fan. Adding a circulating fan removed the heat stratification.
Thermal Management: Thermal Management Design Guide Thermal Management Design Guide Acoustical Noise Decibel Loudness Comparisons Acoustical noise is typically measured by the Sound Pressure Level (Lρ), expressed in decibels and is dependent upon the distance from the source as well as its surroundings.
Thermal Management: Air Conditioners Air Conditioners Sizing and Selection Air Conditioners Air Conditioners Sizing and Selection Air Conditioners Sizing and Selection Overview Before choosing a thermal management solution, you need to carefully consider the specifics of your application in addition to the following factors: •• Fan packages and blowers may introduce ambient contaminants like oil mist and dust into the enclosure •• Heat exchangers cannot cool below the ambient temperature •• Closed-l
Thermal Management: Air Conditioners Air Conditioners Sizing and Selection Air Conditioner Sizing Air conditioners are appropriate for applications in which: •• The temperature inside the enclosure must be maintained at or below ambient temperature. •• Humidity must be removed from the enclosure. •• Ambient air contaminants must be kept out of the enclosure. The following air conditioner sizing procedure applies to uninsulated, sealed and gasketed enclosures in indoor locations. Step 1.

Thermal Management: Fans, Blowers, Louvers and Vents How to Choose a Filter Fan How to Choose a Filter Fan How to Choose a Filter Fan Overview Three overall considerations are applied when selecting a filter fan: •• voltage input •• enclosure protection •• airflow requirement Voltage Input Narrowing the choice of filter fans based on voltage input is quite simple. If the voltage available in the electronics system to power the filter fan is AC, then an VAC filter fan is chosen.
Thermal Management: Fans, Blowers, Louvers and Vents How to Derive Filter Fan Airflow Step 1. Determine Delta-T (ΔT) For example: Delta-T is the difference between maximum desired temperature for the electronics and maximum temperature outside the enclosure. It is important to determine ΔT because cooler air will usually require less filter fan airflow whereas warmer air will typically require more airflow.
Thermal Management: Fans, Blowers, Louvers and Vents How to Derive Filter Fan Airflow Step 3. Determine Free Airflow Then find your cabinet’s heat load along the Y-axis of the chart. In the example from step 2, heat load is 2000 W. Determining free airflow applies the results from steps 1 and 2 to the chart below.
Thermal Management: Fans, Blowers, Louvers and Vents How to Derive Filter Fan Airflow Step 4. Estimate System Impedance Static pressure or system impedance can impact the cooling performance of an air mover. Filter fans work well in electrical cabinets with low static pressure such as a large enclosure with a bare drive and few other components. They do not have enough force to push air through a cabinet with a moderate or high system impedance.
